Server Rail Assembly with Flexible Arm for Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional server devices in limited spaces often lack sufficient space for sliding rails, leading to instability during transport due to unsecured rear sides, which can result in damage from collisions and shaking.
Innovation Solution
A rail assembly with a lateral board, flange, and positioning flexible arms that securely fasten both the front and rear sides of the server, allowing horizontal movement while preventing vertical displacement and ensuring stability during transport.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a conventional sliding rail is used to limit horizontal movement, then horizontal stability is improved, but vertical displacement cannot be prevented and the structure becomes complex
Solution Approach 1:
The positioning function is segmented between the flange (horizontal positioning) and the positioning flexible arm (vertical positioning). This division allows each component to specialize in one direction, achieving both horizontal and vertical stability without requiring a complex combined mechanism.
Solution Approach 2:
The positioning flexible arm integrates both positioning and limiting functions into a single component. It simultaneously provides vertical positioning and limits vertical displacement through its engagement with the server's rear portion, merging multiple functions that would otherwise require separate mechanisms.
2Area of stationary object
If the chassis size is reduced to fit limited space, then space utilization is improved, but there is no sufficient space for slide rail and the server becomes unstable
Solution Approach 1:
The positioning flexible arm utilizes elastic deformation to adapt to different server positions during insertion and removal. The flexible arm can dynamically adjust its position within the positioning slot, providing continuous stability support without requiring fixed rigid structures that would consume additional space.
Solution Approach 2:
The positioning flexible arm acts as a flexible structural element that provides mechanical support and positioning functionality without occupying significant space. Its flexible nature allows it to bend and adapt while maintaining structural integrity, enabling stable server mounting in compact chassis designs.
3Ease of manufacture
If only the front side of the server is fixed to the rail assembly, then installation is simplified, but the rear side remains unsecured and vulnerable to damage
Solution Approach 1:
The positioning flexible arm automatically engages with the server's rear portion through its elastic properties. When the server is inserted, the flexible arm naturally deflects and then snaps into the positioning slot, providing self-securing functionality without requiring additional fastening operations or complex installation procedures.
Solution Approach 2:
The positioning flexible arm changes its physical state from a bent configuration during insertion to a locked configuration when engaged. This parameter change in its shape and position allows it to transition from a flexible insertion aid to a rigid locking mechanism, securing the server rear side automatically.

AI summary
A server device includes a chassis, a rail assembly, and a server. The rail assembly is fixed inside the chassis. The rail assembly includes a lateral board and a flange. The lateral board is arranged vertically, the flange protrudes from one side of the lateral board, the flange is arranged horizontally and extends horizontally in a long strip shape, a positioning flexible arm is disposed on the lateral board, and the positioning flexible arm and the flange protrude from the same side of the lateral board. The server is loaded on the flange and movable along the flange, the server includes a front portion and a rear portion opposite to the front portion. When the server is entirely received in the chassis, the front portion is fixed to one end of the rail assembly, and the positioning flexible arm is engaged with an outer surface of the rear portion.
